Anon who asked about dumping my selfship lore here! Thank you for letting me! This was a lot longer than I thought it would be, my apologies ^^’
TWs for rape, drug mentions, incest (fauxcest, technically, but some would still consider it such), one mention of suicide, and brief mentions of OCD obsessive thoughts ig?
So my F/O is actually an OC of mine who I made because I want more problematic characters. He was also kinda made to help me cope with my OCD? Like, I have horrible intrusive thoughts about drugs, so part of his character is that he does (at least he used to, there's self-indulgent character development on that) stuff like that. I also have intrusive thoughts about my own IRL siblings, which I personally would never act on and frankly make me nauseous when I ruminate on them, so I decided to make my F/O an older step-brother character for my S/I to help me vent that stuff. I also get a wild amount of gender envy from frat boys, so. A lot of his actions are based on toxic frat boy stereotypes. Evil frat boy. He's an awful person who has a history of drugging people at parties for shits and giggles. Sometimes he'd rape them if he was feeling like it, other times he'd just roofie them for fun, record 'em getting all loopy, yadda yadda.
His parents got divorced when he was in middle school and he lives with his dad, up until 12th grade when his dad met the mom of my S/I who was in 7th grade at the time. S/I was really scared of him and he was a huge trigger to S/I's drug-related trauma. F/O is usually not the type to change his behaviours for others, but the little thing was intriguing and he couldn't get to know S/I more until he quit smoking, so he got over that. He won't admit it, but he feels better since quitting.
His attempts to get to know my S/I as family were met with a lot of running away, but S/I eventually sorta warmed up to him a little bit and they started to have a pretty normal sibling relationship. Then in 8th grade, my S/I came out to F/O as ftm and was really scared he wouldn't want to hang out with him anymore. But that's when F/O's non-familial attraction to S/I hit. A sheltered little brother who he gets to take under his wing? Teach him how to do boy stuff? Dress him in his clothes? Show him how boys jerk off? Make him hang out with him and his friends? Hell yeah.
He did end up influencing S/I into growing a spine as he got older, but F/O just found it hot and wasn't bothered too much. Yeah, his little brother does know how to stand his ground now, and it's because of him.
One day after my S/I started TRT, he shamefully came into F/O's room to ask him for help with the spiked sex drive, leading to F/O taking S/I's virginity and trying not to go crazy over it. From then on, any time S/I wanted to get off, F/O told him to just come to him and he'd help.
Where the timeline is now, with F/O and S/I being 23 (24 in October) and 19 respectively, S/I recently came into F/O's room to cuddle since he couldn't sleep. They bantered for a bit before S/I started falling asleep curled up to F/O. F/O was tired of dancing around each other and just being brothers who fucked. He wanted S/I to be his and his alone. He won't act like he hasn't thought about drugging S/I and stealing him away, but he knows how S/I would feel about having drugs that haven't been prescribed to him in his system. Read: violently suicidal. So he woke S/I up to ask how long they were gonna keep acting like nothing else was happening between them.
S/I was confused and sleepy, but he got it together pretty quick and started getting nervous. Asking what if their parents found out, what if people saw them in public and knew them, what about F/O's friends? F/O said they didn't have to tell their parents, and that he'd deal with anyone who saw them in public who recognized them as siblings, and that his friends don't even know they're stepbrothers and think that S/I is just some cute little boytoy that stays over a lot. S/I doesn't question how they thought he was F/O's boyfriend and nothing else despite having known them since 8th grade, i.e. as a child. F/O got uncharacteristically sincere and confessed that he really does like S/I, and that he's tired of what they have going on right now when all he wants is to claim his little brother properly. So S/I decided that they're boyfriends now, and then they kissed and lived happily ever after!! :D
F/O also likes stalking S/I whenever he goes out and dreams about raping his baby brother, but there's always something in the way of him doing it. He'll get his way eventually. Trust 🙂↕️ Something something dressing up and raping surprising S/I in a haunted corn maze around Halloween....
Again, I'm so sorry this is so long. I get a little excited talking about me and Rogue (F/O) since my IRL friends are antis and I have no one to talk about him to.
